I'm afraid to tell you that there is currently no way to start another iOS app on the same device simultaneously. Since the same port will be used for the second app the application crashes after the start. This functionality is not supported at the moment.

There is a feature request in our internal system in regard to starting another iOS app during test execution. Currently, we do not know if and when this feature will be implemented. This depends on various factors. Nevertheless, all reported bugs and feature requests are documented in the release notes, with every new version release of Ranorex.
